Abstract:

In order to find out the rodent population composition and the changes of population dynamics and provide scientific basis for forecast and prevention of population, we analyzed the monitoring of rural rodents in 30 counties (cities, districts) in Guizhou Province from 1984 to 2010. The results indicated that rodents in Guizhou Province belong to 2 orders (Rodentia, Insectivora) 3 Division (Muridae, Cricetidae, Soricidae) and 18 species, mainly in the Muridae, 77.78% of the total number. Oriental species is absolutely dominant species in fauna composition, 66.67% of the total number. In residential area, Rattus norvegicus and Rattus tanezumi are dominant species, respectively, 51.26% and 29.16% of the total number. Mus musculus is common species, 16.80% of the total number. In agricultural areas, Apodemus agrarius is dominant species (paddyfield, dryland), 62.57% of the total number. Rattus norvegicus and Rattus tanezumi are common species, respectively, 12.29% and 14.73% of the total number. They are also dominant species of agricultural rodents in some areas. Apodemus chevrieri is dominant species in the northwestern parts of Guizhou Province. The focal monitoring species in Guizhou Province are Apodemus agrarius, Apodemus agrarius, Rattus norvegicus, Rattus tanezumi and Mus musculus. The number of rodents in residential areas is significantly higher than that in agricultural. Population dynamics showed a downward trend and varies significantly in different year, different period, different months and different seasons. According years forecast and control of agricultural rodents in Guizhou Province, we cleared the technical route of monitoring and integrated control of agricultural rodents and brought up a set of practical monitoring technology and integrated control matching technology of agricultural rodents.
